Glaucoma Maltese-Dogs-disease

This is the condition in which loss of vision occurs because of an abnormally high pressure in the eyes of Maltese-dogs. In most cases there is no other ocular disease. This is known as primary glaucoma and there are two pathologically distinct types, acute and chronic simple. In acute glaucoma, there is an unexpected rise in pressure due to sudden closure of the angle between the cornea and iris where aqueous humour usually drains from the eye of the Maltese-dogs.                                                                       

This is accompanied by pain and marked blurring of vision associated with inflammation of the anterior segment. In the more common chronic simple glaucoma, the pressure rises slowly, commonly without producing pain, and the visual loss is insidious for the Maltese-dogs. The same type of visual loss of the Maltese-dogs may rarely occur in eyes with a normal pressure, this is called low-tension glaucoma. Primary glaucoma occurs increasingly with age and is an important cause of blindness. Secondary glaucoma may occur when other ocular disease damages the normal circulation of the aqueous humour((the watery fluid that fills the chamber of the eye instantly behind the cornea and in front of the lens. It is continually being formed chiefly by capillaries of the ciliary processes. And it drains away into Schlemm’s canal, at the junction of the cornea and sclera)) And causes the intraocular pressure to Rise .               

In all types of glaucoma the eventual problem is to reduce the intraocular (of or relating to the area within the eyeball. An intraocular lens implant is a plastic lens placed inside the eye after cataract extraction to replace the natural lens) pressure. Drops are inserted into the eye of the Maltese-dogs at regular intervals to improve the outflow of aqueous humour from the eye and or to reduce the production of aqueous humour. Drugs used for this purpose include beta blockers (for example  timolol, levobunolol, carteolol), carbonic anhydrase inhibitors (for example  brinzolamide, dorzolamide), alpha-receptor stimulants ( apraclonidine, brimonidine), and latanoprost. If this treatment is ineffective, surgery may be performed to make a new channel through which the aqueous humour may drain from the eye of the Maltes- dogs in sufficient quantities to allow the pressure to return to normal. Such operations are known as drainage or filtering operations.  

                    

This disease Glaucoma very painful and Maltese-dogs that are affected to this disease feel very pain in their eyes they rub their eyes with their paws any kind of other things like trees,walls and furniture.the symptoms of this disease is different to those symptoms that being observed at that stage when Maltese- dogs suffered in this disease. It can be attacked one or both eyes. Many Maltese dogs suffered in light sensitive and they mhide himself in the dark corners or the shade of walls.The organs of Maltese-dogs that affected by this disease are Nervous and sensory organs.
